Exclusion Criteria: * GA in either eye due to causes other than AMD * Participation in other ophthalmic clinical trials or use of any other investigational drugs or devices in study eye or systemically for 6 months prior to enrollment, or anticipated participation in other ophthalmic clinical trials or use of any other investigational drugs or devices in study eye or systemically during the study period * Intraocular inflammation in the study eye * Ocular or periocular infection in the study eye * Media opacity that would limit baseline visual acuity or clinical visualization of the retina at baseline * Hyperautofluoresence adjacent to GA lesion in study eye that is focal only * Previous IVT treatment, history of retinal surgery, or other retinal therapeutic procedures in the study eye * Systemic immunosuppression that may interfere with retinal and cytokine expression including but not limited to glucocorticoids (eg, oral prednisone or dexamethasone); antimetabolites (eg, methotrexate, mycophenolate mofetil, and azathioprine); T-cell inhibitors (eg, cyclosporine, tacrolimus, sirolimus); alkylating agents (eg, cyclophosphamide and chlorambucil); and biologic agents (eg, tumor necrosis factor inhibitors, interferons, lymphocyte inhibitors, and interleukin inhibitors) * Prior history of systemic use of pentosan polysulfate sodium (trade name Elmiron®) * Any ocular or systemic condition that in the opinion of the Investigator makes the subject unsuitable treatment with an investigational agent or that would compromise the safety and efficacy assessments of the trial * An unwillingness to elect to either a) use Age-related Eye Disease Study 2 (AREDS2) formula nutraceutical therapy for the duration of the study or b) choose not to use such therapy for the duration of the study
